1. Field of the Invention
The present invention relates to an electrical connector, and more particularly to an IEEE 1394 electrical connector.
2. Description of Related Art
IEEE 1394 standard, originally developed by Institute for Electrical and Electronic Engineers (IEEE) as a replacement for Small Computer Systems Interface (SCSI), is widely used in peripheral devices of the computer or digital products. Related description can be referred to an article of a magazine CONNECTOR SPECIFIER published on February 1998, entitled Blazing Ahead with 1394, which is submitted herewith by Information Disclosure Statement (IDS). U.S. Pat. Nos. 5,362,249, 6,165,015, D391,551, D390,192 and D410,434 also disclose such IEEE 1394 electrical connectors.
As stated in Blazing Ahead with 1394, the IEEE 1394 standard generally contains two connector systems: a six-circuit I/O connector used in peripheral devices and a four-bay unitized connector generally for internal applications. Following the development of digital video device, for example, digital camera or digital camcorder, a four-circuit I/O IEEE 1394 electrical connector is developed for input/out use of the digital video device. The four-circuit IEEE 1394 electrical connector does not have a power pair of the six-circuit IEEE 1394 electrical connector. U.S. Pat. Nos. D391,551 and D390,192,both issued to Naoyuki Ono, disclose such four-circuit IEEE 1394 electrical connectors. Generally, such connectors are small size so that they are suitable for portable application. However, since lacking the power pair, these connectors cannot be used in electronic devices which are not self-powered.
The six-circuit IEEE 1394 electrical connectors, such as those disclosed in U.S. Pat. Nos. 6,165,015, D410,434 and 5,362,249, have the power pair so that they can be used in electronic devices which are not self-powered. However, these connectors are bulky so that they are not suitable for use in portable devices, such as personal digital assistant (PDA), laptop computer or other hand-held digital devices.
Hence, an improved small size IEEE 1394 electrical connector with a power pair is required to overcome above disadvantages of the conventional IEEE 1394 electrical connectors.
Accordingly, an object of the present invention is to provide a small size electrical connector having power contacts therein so that the connector can be used in a portable electronic device which is not self-powered.
In order to achieve the object set forth, an electrical connector in accordance with the present invention includes a housing, four signal contacts, a pair of power contacts and a shielding. The housing has a forwardly extending mating tongue. The mating tongue defines four receiving channels in a vertical direction and a pair of side surfaces. A groove is defined in each of the side surfaces. Each signal contact comprises a mating portion retained in a corresponding receiving channel. Each power contact comprises a mating portion retained in a corresponding groove of the mating tongue. The shielding substantially surrounds the housing. The connector has a small dimension and can be used in a portable electronic device.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Referring to
The insulative housing 10 is generally rectangular in shape and has a mating face 11 on a front portion thereof, a rear base 13 opposite to the mating face 11 and a mounting face 14 on a bottom portion thereof perpendicular to the mating face 11. The insulative housing 10 comprises an upper wall 15 between a pair of sidewalls 16 thus together forming a receiving space 18 adapted for mating with the complementary connector. The upper wall 15 defines an upper recess 150 adjacent to the rear base 13. Each sidewall 16 defines a projecting rib 160 protruding outwardly therefrom for purposes described hereinafter. The mounting face 14 defines a lower slot 140 in a front end of a middle portion thereof, and a pair of guiding posts 142 (only one shown in
As best shown in
As shown in
The signal contacts 20, best shown in
Like the signal contacts 20, each of the pair of power contacts 30 comprises a mating portion 31, a mounting portion 32 extending rearwardly from the mating portion 31, a retaining portion 33 bent downwardly from the mounting portion 32, and a soldering portion 34 for being soldered on the printed circuit board by surface mounting technology, as shown in
The first shielding 40 and the second shielding 50 are fabricated from metal or other electrically conductive materials. The first shielding 40 comprises a bottom wall 41 and a pair of sidewalls 42 extending upwardly from respective sides of the bottom wall 41. The first shielding 40 is assembled to the housing 10 from the mounting face 14 of the housing 10. The bottom wall 41 of the first shielding 40 defines an engaging tab 410 received in the slot 140 of the mounting face 14 of the housing 10. The engaging tab 410 is devised for electrically engaging with a shielding of the complementary connector when the electrical connector 1 and the complementary connector are mated together. A pair of upper fastening tabs 43 is bent inwardly from top edges of the sidewalls 42. The fastening tabs 43 engage with the upper wall 15 of the insulative housing 10. Each sidewall 42 defines a protrusion 420 projecting outwardly therefrom. A recess 422 is thus formed in the protrusion 420. The recess 422 receives a corresponding projecting rib 160 of the sidewall 16 of the housing 16.
The second shielding 50 is shaped as a rectangular hollow casing. It is used for substantially shielding the subassembly of the housing 10, the contacts 20, 30 and the first shielding 40. The second shielding 50 comprises a mating frame 52 on a front portion thereof, a top wall 54, and a pair of sidewalls 56 extending downwardly from respective sides of the top wall 54. The frame 52 defined a recess 53 in a top face thereof; the recess 53 is used for a polarization purpose. When the subassembly of the housing 10, the contacts 20, 30 and the first shielding 40 is assembled with the second shielding 50, the protrusions 420 of the first shielding 40 are retained in cavities 560 defined in the sidewalls 56 of the second shielding 50. The sidewalls 56 of the second shielding 50 form a pair of retaining tabs 562 each extending inwardly from a rear edge thereof, for being retained in the rear recesses 138 of the housing 10. A retaining portion 58 having a screw hole 580 extends upwardly between the top wall 54 and the mating frame 52. The retaining portion 58 is used for fastening the electrical connector 1 to the complementary electrical connector when mating by a screw. A plurality of retaining feet 564 extends downwardly from a lower side of the sidewalls 56 thereof for being received in corresponding holes of the printed circuit board and soldered thereto.
The advantages of the present invention over the prior art are that each side surface 122 of the mating tongue 12 defines a side groove 128 therein for receiving a power contact 30. The mating tongue 12 thus has a small width; accordingly, the connector 1 has a small dimension and it can be used in a portable electronic device. Furthermore, since the connector 1 has the pair of power contacts 30, electrical power can be transmitted from a host device via the electrical connector 1 in accordance with the present invention to the portable electronic device incorporating the electrical connector 1. Thus, the portable electronic device needs not to be a self-powered device. Accordingly, the present invention can resolve the problems confronted by the prior art connectors.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
